• Appropriate mathematical procedures for estimation of loads.

Context of and specific resources for assessment 

• Assessment of the safe and effective application of knowledge and skill to workplace tasks (performance) must be undertaken using the endorsed Assessment Instrument.
• Assessment of performance must be undertaken either in the workplace or in a realistically simulated workplace setting.
• Assessors must ensure that the assessment in the workplace is organised to ensure that all the required equipment and materials and a suitable working area is made available to suit the assessment and the workplace.
• Assessment must occur under standard and authorised work practices, safety requirements and environmental constraints.
• Assessment is to comply with relevant appropriate standard requirements.
• Applicants must have access to:

Method of assessment 

• Assessment must be conducted using the endorsed Assessment Instruments. These Instruments provide advice on their application.
• The use of 'simulators'  in the assessment of this unit of competency is not acceptable .
• Assessment may be in conjunction with the assessment of other units of competency.
• Assessment methods must confirm consistency and accuracy of performance together with application of underpinning knowledge.
